A clarification question...given the query: create table x (x_id integer, f varchar); create table y (y_id integer, x_id integer, f varchar);
insert into x values(1, 'wibble'); insert into y values(1, 1, 'foo'); insert into y values(1, 1, 'bar'); select y.y_id, case when y.f = 'foo' then 'very good' else (select x.f from x where x.x_id = y.x_id) end from y The documentation states that: "If the SELECT expression does contain variables from the outer query, then the SELECT is reevaluated every time it is needed." Am I correct in assuming that if (using the above example) y.f = 'foo' that the sub-select is considered "not needed" and therefore is not executed?
